Research on the Stability Affected by Digital Process of SPWM Inverter

Abstract:

Digital controlled SPWM inverter has become main-stream in development of SPWM inverter control strategy. But the traditional PID control strategy realized in digital control can’t achieve better performance than in analog control. Process of the zero-order hold & one-step-delay control were researched the effect of zero-order hold & one-step-delay control on the stability of digital control SPWM inverter with quantitative analysis in this paper. Finally relevant simulations and experiments were verified the validity of the theoretical analysis.
